" LENS-MOUNT. i

To all whom it may concern 71is a detail perspective view,

vments in Lens-Mounts,

,Be it known that I, WILLIAM RUHLE- MANN, a citizen of the United States of America, and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain' new and useful. Improveof which the following is a specification.

This invention relates to that type of lens mounts in-which the clips are secured to the lenses without the use of clamping screws, and without y any material encroachment upon the field of vision of the lenses. And the present improvement has for itsy object to provide a simple and efficient structural formation andcombination of parts whereby a strong and effective attachment is ef- Vfected in a convenient and economical manner, all as will hereinafter more fully appear.

In the accompanying drawings z-Figure illustrating -jthe general arrangement of parts in the tion of the mount.

' of radial present invention as applied to an eyeglass. Fig.`2, is a'- seotio'nal view of the lens mount, 3, Ishowing the same in Fig. 3, is a rear eleva- Fig. 4, is a transverse section of the mount, on line ait-ae', Fig. 2. Fig. 5, is a sectionalview of a modified form place upon a lens.

"of mount.

Similar reference numerals indicate like parts in the several views. y Referring to the drawings, 1 represents a portion of an eyeglass lens, which in the present construction is formed with a pair notches '2 in its perimeter, said notches being disposed equidistant from a line representing the major diameter of the lens, as shown. r

, 3 is the box clip of the present construction, formed of gold orother suitable metalA or material, and comprising a curved back portion or web 4, a'pair of side flanges or webs 5, and a pair of transverse engaging tongues or webs 6.4 In the preferred form of the present invention illustrated in Figs. 2, 3 and 4C, the above described webs 2L, 5 and 6, are shown as an integral or one piece formation, it is however within the province of this partof the present invention to make the transverse engaging tongues or webs 6, separate fromthe other webs, `and preferably in the connected form shown in Fig. 5,'

and subsequently brazed or riveted to the back portioiror web 4c, of the box clip.

The curved back portion or web et, will preferably have av curve of a lesser radius than the radius of the end lens l, in order4 to provide a semi-lunar cavity at the edge of the lens for holding a body oftheceinenting composition employed in securing the clip in place, and thereby attain a very effective unicnof the parts, and so that the bearing between the parts will only be near the respective ends of the web 4, as illustrated in Fig. 2 to confine the cementing composition in place and materially aid in attaining a strong and durable attachment of the eyeglass parts. The side webs will their greatest width in proximity to the engaging tongues or webs 6,l with a comparatively narrow central portion 7 separating said wider portions, and permitting of a limited flexure or bending of the clip, when required in the initial litting of the clip to the lens. r

In the preferred form of the present invention shown in the drawings, the attachment of the transverse engaging tongues or webs 6, is wholly with the back web ll, leaving the side edges of said tongues or webs 6 free from any connection with the side webs o.c Such construction permits of free swinging apart of the free ends of said tongues or webs so that they may lreadily pass over the wider outer portion of the segmentV of the lens formed by the radial notches 2, in the operation of connecting the clip to the lens. In actual use, a suitable cement will be employed between theI interior of the clip and the exterior of the lens, to aid the niechanical construction above described in eifecting a strong and substantial connection between the parts.

8 is the usual attaching box, in which an end of the eyeglass bridge 9 is secured in any usual manner, and said box 8 may be disposed at the rear of the clip 3, as shown in Fig. l, or in anyT other usual position on the clip which the judgment of the optician may indicate.

Having thus fully described niy'said in' vention, what I claim as new and desire'to secure by Letters Patent, is

l. A lensmount, comprising a box clip,

web, a pair of. side webs and a pair of transverse attaching webs, providing in Connection with a lens a closed c avity adapted to retain a cementing body, said attaching webs being adaptedl to be sprung into radial notches in the perimeter of a lens, each side web comprising a pair of widenedportions 'connected together by a narrow central portion adapting the clip to ybe symmetrically bent to lit varying curvatures of the perimeter of the lens.

3. A lens mount, comprising a box clip formed with a curved and continuous back web, a pair ot side webs and a pair of transverse attaching webs connected solely to the back web and free from connection with the side webs providing in connection with a lens a closed cavity adapted to retain a cementing body, the said attaching webs being adapted to be sprung into radial notches in the perimeter of a lens, each side web comprising a pair of widened portions connected together by a narrow central portion adapting the clip Lto be symmetrically bent to lit varying curvatures of the perimeter of the lens.

Il. .A lens mount, comprising a 'box clip formed with a curved and continuous back Web, the radius of which is smaller than the perimeter of the lens to which attachment is to be made, a pair of side webs, and a pair of transverse attaching webs, said attaching Webs being adapted to be sprung into radial notches in the perimeter of a lens, the said back and side webs providing in connection with a lens a closed cavity adapted to retain a cementing body.

5. A lens mount, comprising a box clip formed with a curved and continuous back web, the radius of which is smaller than the perimeter of the lens to which attachment is to be made, a pair of side webs, and a pair of transverse attaching Webs connected solely to the back web and free from connection with the side Webs, the said attaching Webs being adapted to be sprung into radial notches in the perimeter of a lens, the said back and side webs providing in connection With a lens a Aclosed cavity adapted to retaina cementing body.

6. A lens mount, comprising a box clip formed with a curved and continuous back Web, the radius of Which is smaller than the perimeter of the lens to which,attachment y is' to be'made, a pair of side Webs, anda pair of transverse attaching Webs, said attaching Webs being adapted to be sprung into radial notches in the perimeter of a lens,

the said back and side Webs providing in connection with a lens a closed cavityadapted to retain a cementing body, each side web comprising a pair of widened portions connected together by a narrow central portion.

7. A lens mount, comprising a box clip formed with a curved and continuous back web, thev radius of which is smaller than the perimeter of the lens to which attachment is Vto be made, a pair of side webs, and a pair of transverse attaching Webs connected solely to the back-Web and free trom connection with the side webs, the said attaching webs being adapted to be sprung into radial notches in the perimeter of a lens, the

said back and side webs providing in connection with a lens a closed cavity adapted to retain a cementing body, each side web comprising a pair of widened portions connected together-by a narrow central portion. Signed at Chicago, Illinois, this 9th day of August 1913.
